This special cover is a tribute to a great astronomer Raja Sawai Jai Singh,the founder of city of Jaipur & creator of world renowned heritage of "Jantar Mantar-Jaipur".
The Jantar Mantar, in Jaipur, is an astronomical observation site built in the early 18th century. It includes a set of some 20 main fixed instruments. They are monumental examples in masonry of known instruments but which in many cases have specific characteristics of their own. Designed for the observation of astronomical positions with the naked eye, they embody several architectural and instrumental innovations. This is the most significant, most comprehensive, and the best preserved of India's historic observatories. It is an expression of the astronomical skills and cosmological concepts of the court of a scholarly prince at the end of the Mughal period.
The 5 INR stamp on the right corner was issued in 2009 showing St.Anne Church,that is a religious monument located in Santana, Goa, India. It is an example of baroque architecture and it is by far the most exquisite and the largest surviving monument of its kind in all of Asia.
